There are busy streets in Holland as well. Such more complex restrictions are perfectly possible with the Dutch style signs. Northern Europe goes by traffic signs adhering to Vienna convention, and while rules are not always that simple, getting the basic message does not require you to read the local language. The signs are standardised within nations, and not that different across nations in EU.

Let's take an example (Google Maps link below). The round sign with blue background with red stripe over it is "no parking", and the additional sign below says "payment required during 9-20 hours weekdays, 16-20 hours Saturdays, 16-20 hours Sundays, other times free parking", then "price zone 2, maximum parking time with payment is 2 hours", then "free parking with resident parking permit for zone H". And the blue sign is "payment machine that way".
